对成矿溶液性质的认识是成矿理论和成矿预测的基础。本文用云南腾冲热泉水、勐野并钾盐卤水、青岛海洋水、贵州赤天化含油气水、贵阳雨水以及从贵阳森林公园腐殖土中提取的含腐植酸的水溶液，和自配的pH＝1．0的含氯酸性水，对西南地区不同岩性的四种矿源岩样进行了加温浸泡溶解实验。另外还利用表生风化淋滤模拟实验装置对该四种矿源岩样进行了三种不同大气雨水的风化淋滤模拟实验。实验结果表明酸雨和酸性水最容易形成高含量的成矿溶液；含腐植酸的水有时对多种金属也能形成较高含量的合矿溶液。但现代雨水、腾冲火山热泉水、勐野井钾盐卤水、青岛海洋水、贵州赤天化含油气水等近中性和偏碱性的表生水对Fe、Mn、Cu、Pb、Zn、等常量金属元素几乎不能形成高含量的合矿溶液；当溶液中存在强络合剂时，可能对某些贵金属和稀有、分散元素的搬运和成矿具有较重要意义。
The understanding of the nature of ore-forming solution is the basis of metallogenic theory and metallogenic prognosis. In this paper, Yunnan Tengchong hot springs, Meng wild and potassium salt brine, Qingdao Ocean Water, Guizhou Chitianhua gas and water, Guiyang rain and humus from Guiyang Forest Park containing humic acid aqueous solution, and self-formulated pH = 1.0 of the chloric acid-containing water, the Southwest of the different lithology of the four source rock samples were heated immersion dissolution experiments. In addition, three different types of atmospheric rainwater leaching simulation experiments were carried out on the four ore-source rock samples using supercritical weathering leaching simulation experiment equipment. The experimental results show that acid rain and acid water are the most likely to form high content of ore-forming solution; humic acid-containing water sometimes can also form a higher content of ore solution for a variety of metals. But modern water, Tengchong volcanic hot spring water, Meng Yejing potash brine, Qingdao ocean water, Guizhou Chitianhua oil and gas water and other near neutral and alkaline water of Fe, Mn, Cu, Pb, Zn, etc. It is almost impossible for constant metal elements to form a high content of ore-forming solution. When strong complexing agent exists in the solution, it may be of great importance to the handling and mineralization of some precious metals, rare and dispersive elements.
